SPECIFIGATION forming part of Letters Patent No. 494,74*?,- dated April 4, 1893.

Application led December 18, 1891. Serial No. 415,466. (No model.)

To all whom it may concern,.-

i Beit known that I, XVILLIAM E. SLmeH'nand State of ivisconsin, have inventedV certain new and useful Improvements in Swinging- `Ireadles; and I do hereby declarel that the following is a full,l clear, and exact description My invention relates to certain new and useful improvements in F swinging treadles for foot power machines and consists inthe matters `hereinafter described and pointed out in the. appended claims.` l

In the accompanying drawings illustrating taken on line 2-2 of Fig. 1. Fig. is a detail sectional view `of one of the parts, taken on line 3 3 of Fig.f1. Figa. is another detail sectional viewofsaid part taken on line Fig.v5;' is another` detail sectional View taken ori line 5-5 of Fig. l.

' taken on line 6--6101 Fig. l. Fig. 7. is another detail view of one of the'parts. Fig. 8. is a horizontal sectional view taken on line 8-8 of Fig. 2.

In said drawings:'-A represents the table or top of the machinaB B the legs, C y wheel and D the connecting rod or pitman which transmits motion from the treadle to said iiy wheel. I

E is a roel; arm secured at one end tothe lower end of the connecting rod or pitman as at ci and at its other end provided with a suitble clamp E for engaging with a sleeve F which is revolu bly supported in the lower por'- tion of the machine'frame. This clamp E is conveniently made in the form of a split ring adapted to grip the sleeve F and drawn togetherby means of a bolt e. As an additional means for securing said clamp upon the sleeve F, a set screw e' is provided which rmly engages with the surface of said sleeve and edectually prevents said clamp from slip- The sleeve F is conveniently supported upon a rod G supported in the lower y part of the frame ofthe machine in any sut l the opposite ends of the sleeve F.

able or desired manner, as by the hangers or brackets H H secured adj ustably to the frame by bolts h passed through the frame and engaged with slots h' in said hangers or brackets. Upon the rod G are provided suitable conical bearing pieces G Gadj ustable lengthwise of said rod and held in their adj usted positions by set screws g g, said conicalvk pieces being arranged to engage with correspondingly recessed bearing surfaces f f formed in The rod G is conveniently screw threaded at its ends and secured to the hangers or brackets HH by nuts g g" as shown in the drawings. Arms FF project from the sleeve F and are connected by means of linlrsF2 F2 with the hanger of the treadle.

Y The hanger J by which the treadle is suspended from the top or the frame of the machine, comprises a lower portion J bifnr' cated as shown and an upper portion K adv `justably secured togetherin any suitable manner, as by means of the construction illustrated in the drawings in which an upwardly 'projecting arm j is provided upon the 'upper end of the lower section l', said arm being provided with a longitudinal channel or groove j withinwhich adcwnwardly pro-l jecting arm 7c on the upper part K is engaged, and ga bolt It is passed through said arm lo and a slot (i2 in the arm j so as to retain the upper and lower portions of the hanger in their adjusted positions. At the lower end of the hanger, between the two arms J J, is secured the foot piece or treadle l, said treadle being provided with upturned ears i upon its opposite sides which ears are provided with grooves 'i' t" upon their outer sides in which the lower ends of the arms J J rest and are secured by bolts i2 i2 so as to hold the treadle firmly in position between said arms. The upper end of the section Kef the hanger is provided with hooks K K arranged to engage with a transverse rod L secured to the lower side of the table or to the frame of the machine in any suitable manner.

, In the particular form of construction illustrated in the drawings, this rod L is secured in bearings m m in the lower ends of hanger blocks M.
